The question in the image is asking:

"Чему равен определитель от произведения матриц?"

This translates to:
"What is the determinant of the product of matrices equal to?"

The answer choices are:

1. Сумме определителей (Sum of determinants)
2. Частному определителей (Quotient of determinants)
3. Произведению определителей (Product of determinants)

Correct Answer:

The determinant of the product of matrices is equal to the product of their determinants.

So, the correct answer is:
"Произведению определителей" (Product of determinants).

Let me know if you'd like a detailed explanation or have any other questions.

Here are some related questions:

1. What is the formula for the determinant of the inverse of a matrix?
2. How does the determinant help in solving systems of linear equations?
3. What happens to the determinant if a matrix is transposed?
4. What is the determinant of a diagonal matrix?
5. How can determinants be used to check matrix invertibility?

Tip: The determinant is a useful property to assess whether a matrix is invertible or singular (det = 0 means singular).
